Apparatus, methods and systems for nano/micro machining. A lathe head has a microscopic pivot aperture for seating a conical tip. The conical tip is carried on a turnable part at one end thereof and is polished down to a microscopic apex. The microscopic pivot aperture is dimensioned for seating the concentric tip in the pivot aperture such that an apex of the conical tip protrudes through and beyond the aperture to a position in close proximity with the aperture. A driver system can comprise a rotator for axially rotating the turnable part, including the conical tip seated in the pivot aperture, and a forward pressure applicator for concurrently applying forward pressure to the conical tip in the direction of the pivot aperture. A light/particle beam system can be utilized to machine the rotating conical tip and the rotating turnable part, including the tip, can be easily removed after machining.
